"I just know that I'm doing what I was put on this earth to do," Julie Weiss said.

Julie Weiss lost her father to pancreatic cancer in Nov. of 2010 and found her calling.

"I didn't realized how under -funded it was, and what a deadly disease it was," Weiss said. "I thought, I'm going to do something big and make a difference.

Volunteers from "Team Hope" a Pancreatic Cancer Action Network greeted Julie and her husband as they arrived at the Duluth International Airport.

"The lifestyle is going from city, to city, to city," David Weiss said. "She doesn't run. She doesn't train anymore. She may run in water but it's really all about marathon recovery."

Grandma's Marathon marks number ten on her quest to run 52 marathons in 49 weeks.

"My father is always the wind at my back," Julie Weiss said. "He is in my heart. He helps me through every marathon, I can feel his energy, I can feel his spirit, I feel his love. I wouldn't be able to do this if it wasn't for him, and do it with so much passion, enthusiasm and fun."

So far, the Marathon Goddess has raised more than $100,000 to help fight Pancreatic Cancer.

Her goal is to raise $1 Million.

"And I'm not stopping there, I'm not stopping until we find a cure," Julie said.
